就常用显存管理API来说,由于编程人员只能获取到显存的虚拟地址,如果有动态调整显存大小的需求(比如GPU上vector扩容),用户必须显式地申请更大的一块显存,并从原始显存中复制数据到新显存,再释放原始显存,然后继续跟踪新分配的显存地址,这样的操作通常会导致应用程序的性能降低和较高的显存带宽峰值利用率。 在CUDA 10.2...

GPU memory models WDDM v2 supports two distinct models for GPU virtual addressing,GpuMmuandIoMmu. A driver mustopt-into support either or both of the models. A single GPU node can support both modes simultaneously. GpuMmu model In theGpuMmumodel, VidMm manages the GPU memory management unit ...
A respective vGPU request includes a GPU memory requirement. GPU configurations are determined in order to accommodate vGPU requests. The GPU configurations are determined based on an integer linear programming (ILP) vGPU request placement model. Configured vGPU profiles are applied for vGPU enabled ...
One embodiment of the present invention sets forth a method for accessing, from within a graphics processing unit (GPU), data objects stored in a memory accessible by the GPU. The method comprises the steps of creating a data object in the memory based on a command received from an applicati...
(if it doesn’t support it already) memory allocated with the CUDA Virtual Memory APIs, so if your application leverages CUDA-Aware OpenMPI, you may not need application changes to leverage that support, but it may require a certain version of CUDA-Aware OpenMPI (I’m not sure exactly what...

With the advent of features like TurboCache and HyperMemory (and now graphics memory virtualization), hardware developers are already prepared to handle much larger latencies than we've seen in the past. The ability to preempt a process on the GPU will only increase the potential latency that ...

这个和四叉树还有一个问题,就是如何设计一个GPU友好的数据结构也是个问题。 1.2 Texture Filtering 由于虚拟纹理并没有完整加载,所以各种采样过滤在page的边界会有问题,我们需要自己设计解决这些问题的方法,适当的使用软实现的采样。 1.2.1 Bi-linear Filtering 这个解决方案比较简单,就是给physical page加上一个像素...
